Immutable positions itself as the first layer-two scaling solution for NFTs on Ethereum. According to Immutable, its blockchain does away with Ethereum’s limitations like low scalability, a poor user experience, illiquidity, and a slow developer experience. Instead, users benefit from instant trading and massive scalability while enjoying zero gas fees for minting and trading NFTs without compromising user or asset security. To achieve that, Immutable is built with STARK zk-rollups, a technology that Vitalik Buterin considers Ethereum to be “all-in on.”
